This is pretty clearly more than just departure from controlled flight. I was on the ground rolling out and tapped the brakes, then this happened. Note the insane bending of the wings - I have the sim’s internal crash damage detection turned off, since it’s generally pretty much useless. So whatever happened must have triggered some mathematical glitch and some insane bending/twisting forces on the wings, the net result of which exceeded 1G vertically, as the more the plane spun around, the higher into the air it moved.
